Remote Streaming Over VPN

Hi everyone!

My knowledge of networking is elementary at best, so please bare with me.

What I’m trying to accomplish is to set up Infuse on my family’s ATV so that they can stream content from my NAS.

The problem I find myself in is that I have been reading that just port forwarding access to my NAS is not recommended since it could lead to malicious attacks. Additionally, I’ve been reading that WebDAV isn’t all that safe either, so I don’t particularly want to go down that road.

I have OpenVPN set up so that I can access my NAS away remotely but how can I do the same with my parents ATV? How can I setup the share on their Infuse with VPN access so that there is no chance of malicious activity? Is this even the right way to go about it?

Any other suggestions would really help! Thanks!
